1. Generalguidelines
ThisOperatingmanual,includingspecifications,isauser’sguideforthecomputerinfraredimagingdevice
forexaminationsinreal‐time,modelTkVr‐IfP"SVIT"(hereafterreferringtoasInfraredcameraSVIT).
ReadthisOperatingmanualbeforeutilizingtheInfraredcameraSVIT.
2. Utilization
2.1.InfraredcameraSVITisintendedforobtainingofthethermalimageofpatients(thermogram)and
measurementofthetemperatureatanypointofthebodyofpatientwithoutthephysicalcontact
withhim/her.

Infraredcameraisusedin:oncology,therapy,urology,mammalogy,traumatology,angiologyand
otherregionsofmedicinefortheearly,preventivediagnosisofawholeseriesofdiseasesbefore
theappearanceofcomplaintsofpatientanddestructivechangesinthecloths

Infraredcameraisdevelopedwiththeuseoflatestachievementsinthetechnologyofthe
semiconductordetectorsofinfraredradiation.
Thedevicehasanumberofnewdiagnosticabilities.

2.2.Utilizationofthedeviceisabsolutelyharmlessforboththepatientsandmedicalpersonnel.
Thereforethemeasurementprocedurecanbeperformedrepeatedly.
Theresultsofmeasurementsaremappedontothescreenofpersonalcomputer,areprocessedby
softwareofthecameraandarememorized.
Theinfraredcameraisintendedforperformingexaminationsinhealthcentersandclinics.

2.3.TheinfraredcameraisdesignedinaccordancewithclimateconditionsofEUstandards,butshallbe
usedat22‐26Ctemperature,atmospherepressureof630‐800mmHgandrelativehumidityshall
notexceed80%.
2.4.Nooutsidesourcesofinfraredradiation(electricalheatinginstruments,incandescentlamps)canbe
presentinthediagnosticroom.Straightsunlightalsostronglyinfluencesthequalityoftheobtained
thermograms;thereforeblindsshouldbeinstalledonthewindows.

6. Safetymeasures
TheInfraredcameraSVITcomplieswiththerequirementsoftheEUstandards.Thesafetymeasuresfor
InfraredcameraSVITaresimilartothegeneralsafetymeasuresforanyelectronics.TheInfraredcameraSVIT
isgroundedbycontactingsolderpadsthatareinthetwo‐pinplug.Devicesconnectedtotheinfraredcamera
SVIT(printer)mustcomplywiththerequirementsoftheEUstandards.
Theinfraredcameramustbeconnectedtothepowersupplybytripolarseparatedsockets.
7. Setup
TheinfraredcameraSVITmustbeusedindoorsandallclimaticrequirementsdefinedinOperatingmanual
mustbemet.TheinfraredcameraSVITistransportedinaplasticbox.Thedevicemustbeunpackedindoorsat
roomtemperature.

7.1. Opentheboxandtakeoffthepolyethylenecoverfromthecamera.
7.2. Fastenthermal‐visioncameratothestand.
7.3. ConnectthecameratothecomputerbythestandardUSB2.0cable.
7.4. Fillthecryostatwithliquidnitrogen.
7.5. Startthecomputer.
7.6. StarttheSibThermsoftware.
7.7. Beginthemeasurements(inaccordancewiththeinstructionsfortheinstrument)
7.8. Attheendofmeasurementsdisconnecttheinstrument(afterturningofftheinstrument,closethe
SibThermsoftwareandturnoffthecomputerbystandardmeans.

8. Measurementprocedure
Forconductingofthemeasurementstheinfraredcameraisdirectedtopatient.Thecontactofpatientwith
thecameraisnotrequired.Thedistancebetweenthecameraandthepatientisdeterminedbythesizeof
region,whichisgoingtobevisualizedonthethermogram.
Aftertheappearanceofanimage,bytherotationofthefocusring,whichislocatedunderthedevicelens(in
thefrontsectionoftheinstrument),itisnecessarytofocusimagetobecomesharp.
Controlofinfraredcameraandconductingofmeasurementsiscarriedoutthroughthedialoguewiththe
SibThermsoftware.

9. Maintenance
Maintenanceshallbecarriedoutinordertopreventdamages.ReadSafetyMeasuressectionofPassport
beforecarryingoutmaintenance.

Followingmaintenancetypesarerequired:
Day‐to‐daymaintenanceisperformedbymedicalpersonnelaccordingtosection7;
Annualmaintenanceisperformedbytechnicalpersonnelonceayear.
Annualmaintenanceincludesexaminingofcameraunits,andtechnicalconditionofcamera.
Incaseofmalfunction,thedeviceisrepairedbyrepresentativesofthemanufacturer.
